Similar Grammar Points

• Noun はともかく（として）: "Leaving aside Noun; apart from Noun"
  • Used to indicate that something is not the main point of focus. Example:
• 価格はともかく、デザインが気に入った。
  • "Leaving aside the price, I liked the design." Difference: While both expressions contrast two things, ならいざ知らず emphasizes that while something might be acceptable in one case, it's not in another. はともかく downplays the importance of the first noun.
